今天接到了一个从Excel内读取图片的需求,在网上查找了一些资料,基本实现了本身的需求,不过因为查到的一些代码比较久远,不能直接移植到本身的项目里,须要稍加改动一下。php
这里介绍一下分别使用phpspreadsheet和PHPExcel扩展库来实现读取Excel内图片的功能:html
首先安装phpspreadsheet,因为线上服务器PHP版本是PHP5.6,因此须要安装兼容PHP5.6的版本,这里安装1.8.2版本shell
composer require phpoffice/phpspreadsheet=1.8.2
而后就能够在项目里使用了服务器
use PhpOffice\PhpSpreadsheet\Cell\Coordinate; use PhpOffice\PhpSpreadsheet\IOFactory; $imageFilePath = './uploads/imgs/'; //图片本地存储的路径 if (!file_exists($imageFilePath)) { //若是目录不存在则递归建立 mkdir($imageFilePath, 0777, true); } try { $inputFileName = './files/1.xlsx'; //包含图片的Excel文件 $objRead = IOFactory::createReader('Xlsx'); $objSpreadsheet = $objRead->load($inputFileName); $objWorksheet = $objSpreadsheet->getSheet(0); $data = $objWorksheet->toArray(); foreach ($objWorksheet->getDrawingCollection() as $drawing) { list($startColumn, $startRow) = Coordinate::coordinateFromString($drawing->getCoordinates()); $imageFileName = $drawing->getCoordinates() . mt_rand(1000, 9999); switch ($drawing->getExtension()) { case 'jpg': case 'jpeg': $imageFileName .= '.jpg'; $source = imagecreatefromjpeg($drawing->getPath()); imagejpeg($source, $imageFilePath . $imageFileName); break; case 'gif': $imageFileName .= '.gif'; $source = imagecreatefromgif($drawing->getPath()); imagegif($source, $imageFilePath . $imageFileName); break; case 'png': $imageFileName .= '.png'; $source = imagecreatefrompng($drawing->getPath()); imagepng($source, $imageFilePath, $imageFileName); break; } $startColumn = ABC2decimal($startColumn); $data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName; } dump($data);die(); } catch (\Exception $e) { throw $e; } public function ABC2decimal($abc) { $ten = 0; $len = strlen($abc); for($i=1;$i<=$len;$i++){ $char = substr($abc,0-$i,1);//反向获取单个字符 $int = ord($char); $ten += ($int-65)*pow(26,$i-1); } return $ten; }
能够看到,图片被读取并存到了本地服务器中composer
PHPExcel实现从Excel文件里读取内容的方法和phpspreadsheet几乎同样,笔记phpspreadsheet就是在PHPExcel基础上写的,不过PHPExcel因为已经被废弃了,因此建议优先使用phpspreadsheet,若是原来项目里一直使用了PHPExcel也能够继续使用PHPExcel的方法ide
use PHPExcel_IOFactory; use PHPExcel_Cell; try { $inputFileName = './files/1.xlsx'; $inputFileType = PHPExcel_IOFactory::identify($inputFileName); $objReader = PHPExcel_IOFactory::createReader($inputFileType); $objPHPExcel = $objReader->load($inputFileName); } catch (\Exception $e) { die('加载文件发生错误:"'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage()); } $sheet = $objPHPExcel->getSheet(0); $data = $sheet->toArray(); //该方法读取不到图片,图片需单独处理 $imageFilePath = './uploads/imgs/'; //图片本地存储的路径 if (!file_exists($imageFilePath)) { mkdir($imageFilePath, 0777, true); } //处理图片 foreach ($sheet->getDrawingCollection() as $img) { list($startColumn, $startRow) = PHPExcel_Cell::coordinateFromString($img->getCoordinates()); //获取图片所在行和列 $imageFileName = $img->getCoordinates() . mt_rand(1000, 9999); switch($img->getExtension()) { case 'jpg': case 'jpeg': $imageFileName .= '.jpeg'; $source = imagecreatefromjpeg($img->getPath()); imagejpeg($source, $imageFilePath.$imageFileName); break; case 'gif': $imageFileName .= '.gif'; $source = imagecreatefromgif($img->getPath()); imagejpeg($source, $imageFilePath.$imageFileName); break; case 'png': $imageFileName .= '.png'; $source = imagecreatefrompng($img->getPath()); imagejpeg($source, $imageFilePath.$imageFileName); break; } $startColumn = ABC2decimal($startColumn); $data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName; } var_dump($data); public function ABC2decimal($abc) { $ten = 0; $len = strlen($abc); for($i=1;$i<=$len;$i++){ $char = substr($abc,0-$i,1);//反向获取单个字符 $int = ord($char); $ten += ($int-65)*pow(26,$i-1); } return $ten; }
